I currently have NGK BR7EF spark plugs in my car because of my nitrous setup. I have about 2k on them and have been DDing my car with them without any problems....except every once in a while on a hot day when I hit a few stop lights one after another coming to a stop it will idol down to 500rpms for a few seconds then idle back up...

In a few weeks im going to be taking my car to myrtle beach, SC (910 miles one way) and I was just wondering what your opinions would be on this? Should I put in TR55's for the drive? obviously most of it is highway but I dont want to be 900+ miles from home and ending up fouling some plugs and what not...like I said, I only have had them in my car for 2k so I dont really know how the act on very long drives. They are gapped ar .032

you should be fine

 

I ran them in my Cam car with no problems. The trick is just not letting the idle or part throttle get too rich with them.

I might grab another set of br7's just in case. If they happen to foul,well you got another set,they shouldnt but why not be safe. If they dont you have a clean set for tuning our just the replacements when that time comes.

 

You should be fine with them on the trip, but if you wanted to you could out the 55's in there. Just remember if you change the plugs to the 55's you can't be sprayin.

 

I just did the entire Power Tour on my BR7EF's, you'll be just fine.

 

yes, im well aware of this....and this is what I was thinking but if you think it shouldnt be a problem then im worried about nothing!!

 

power tour?? im not familiar....

 

I daily drive them on my truck, about 5k miles with no issues, idle tuning needs to be good though.

 

In my Vette I NA cruise with them. When I spray my 200 shot I swap to the 8's

 

I think you will be fine on the 7's

He means the Hot Rod Power Tour
